DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 464,415, dated December 1, 1891. Application filed June 23, 1891. Serial No. 897,216. (No model.) Patented in England June 24, 1890, No. 9,827-

To all whom it may concern:

Be it known that I, CHARLES MCGUIRE BATE, a subject of the Queen of Great Britain, and a resident of London, England, have in vented certain new and useful Improvements in Looks, (for which I have obtained a patent in Great Britain, No. 9,827, bearing date June 24, 1890,) of which the following isaspecification, reference being had to the accompanying drawings.

My invention is designed to provide an improved lock or fastening device which can be temporarily employed in combination with a drawer, door, or the like to prevent the opening of the same by unauthorized persons.

In carrying my said invention into practice I provide a casing, to which is hinged or jointed a thin plate having one or more barbs, catches, or points, which, when the said plate is inserted into the crevice between a drawer and its case, or a door and its jamb, or the like, will engage in the wood-work and prevent the withdrawal of the said plate while the drawer, door, or the like is closed. The said casing is provided with lock mechanism comprising a bolt, catch, lever, or other suitable device for securing the said casing at right angles or approximately at right angles to the said plate, and thus preventing the opening of the said drawer or door.

Inthe accompanying drawings I have shown how my said invention may be conveniently and advantageously carried into practice.

Figure 1 is a front elevation, partly in vertical section, illustrating one form of my improved lock or fastening device, a portion of the casing being removed. Fig. 2 is a vertical section on the line 00 m, Fig. 1. Fig. 3 is a vertical section showing a portion of a table and drawer with my lock or fastening device applied thereto.

Like letters indicate corresponding parts throughout the drawings.

A is a plate having one ormore barbs or teeth A or other suitable points or projections. The plate A is connected by a hingejoint A A to a casing B, somewhat resem= blin g that ofan ordinary padlock, so that when 50 the said casing B is moved or adjusted into line with the said plate the under surface of the said casing B will be flush or in the same plane with the under surface of the plate.

0 is a bolt, catch, or lever pivoted at O to the casing B. O is an extension of the said bolt, catch, or lever C, so arranged that when the plate A is at right angles or approximately at right angles to the casing B the said extension will enter a hole, notch, or recess A, formed in the eye A in which it will be held by a spring D, one extremity of which is secured to the casing B, and the other extremity whereof engages with an extension 0 of the said bolt, catch, or lever O.

B is a key-hole formed in the casing B, and B is a pin firmly secured to the rear wall of the said casing, so that it will enter the barrel of the key. To unlock or unfasten the device, the key (which may be of any ordinary and suitable construction) is inserted into the key-hole B and turned, as indicated in dotted lines in Fig. 1', until the bit thereof engages with the extension 0 of the bolt, catch, or lever C, and moves the latter so as to compress the spring D and disengage the extension 0 from the notch or recess A In Fig. 3 I have shownv my improved lock or fastening device applied to a drawer and locked or secured so as to prevent the opening of the said drawer by unauthorized persons. When the bolt, catch, or lever O is disengaged from the notch A and the casing B is raised or moved into the position shown in dotted lines in the said figure, the drawer can be pulled out, as usual. The point or points A are preferably made flexible, so as to enable the plateA to be inserted into the crevice between the drawer and its case While the said drawer is closed.

AlthoughI have hereinbefore described and 0 illustrated my improved lock or fastening device as applied to a drawer, it is obvious that it is also advantageously applicable to doors or the like.

The points or projections upon the abovementioned plate are in someinstances hinged or may be made removable, thus enabling the said points to be readily replaced in case of damage or wear. Instead of the said points or projections, or in combination therewith, roo

I sometimes provide one or more holes for enabling the said plate to be secured in posishell about its hinge, as and for the purpose specified. v

2. A lock or fastening device comprising a barbed plate for fixing or holding the device in position, a shell hinged to the said plate and constituting the fastening-piece proper, and a spring-catch pivoted in the said shell and adapted to engage in one position of the 20 shell With a notch in the hinge of the barbed plate, as and for the purpose specified.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

CHARLES MCGUIRE BATE.
